Definitions

  • the invention is concerned with a system for automatic adjustment to external mirrors when driving in curves in accord with claim 1 and the invention is additionally concerned with an external mirror with a system of the above type in accord with claim 15 .
  • the turning motion of the vehicle about its vertical axis can be determined by a turn-rate sensor operating on the principle of a gyroscope
  • the functioning of the tracking system cannot be impaired by, for instance, contaminations, such as invariably enter in the case of commercial vehicles nor by magnetic fields due to the electrical usage in the vehicle.
  • contaminations such as invariably enter in the case of commercial vehicles nor by magnetic fields due to the electrical usage in the vehicle.
  • the mirror adjustment apparatus of the tracking system is the electro-magnetic mirror adjustment system of a conventional external rear view mirror, so that any additional components are avoided.
  • the adjustment of the external mirror is made continually in accord with the sensor measured turning of the vehicle about the vertical axis. In this way backward mirror movements, which could irritate the driver are avoided.
  • the travel speed of the vehicle is taken into consideration as an input to the tracking of the mirror. That is, at a greater driving speed, the adjustment is effected more rapidly than at lower driving speeds.
  • the tracking movement during curve driving is done only in a definite speed range between a minimal speed and a maximum speed.
  • the speed of the vehicle is determined by direct branching from an existing speed signal which is normally found in vehicles, which signal is diverted to the control device.
  • An additional speed sensor is superfluous.
  • the speed of the vehicle, with which the external mirror is adjusted corresponds to, i.e. is proportional to the turning speed of the vehicle about its vertical axis.
  • the evaluation of a driving speed becomes superfluous.
  • the tracking of the external mirror corresponds to the determined rate of turning between a zero-point and a maximum allowable angle in two opposite turning directions. Then the sensor detects a turning about a vertical axis upon the beginning of a curve, then the deflection of the external mirror is to the outside, and if the sensor detects, that the vehicle again resumes a directly forward movement, then the external mirror is reset in the opposite direction to the zero-point.
  • the system for tracking is subject to manual disconnection. This is of advantage in the course of maneuvering or if the driver feels himself irritated by the automatic tracking.
  • the turn rate sensor for tractor trailers is installed in the cab.
  • the trailer itself no components of the invented tracking system have been provided. This would make sure, that optional trailers can be employed, since the system is exclusively situated in the cab.
  • the tracking system is integrated in a conventional external mirror installation with electromotive control possibilities.
  • the external mirror complete with automatic tracking can be offered as a complete system.
  • FIG. 1 a schematic presentation for the explanation of the fundamental principles of an automatically controlled, tracking mirror in curved driving
  • FIG. 2 a block, interconnection diagram of an example embodiment of the present invention
  • FIG. 3 a schematic presentation of the integration of the system of the invention into an external mirror for commercial vehicles.
  • FIG. 1 shows a tractor-trailer 2 , which is comprised of a tractor 4 and a trailer 6 in the course of a left turn at an intersection, that is to say, upon making a left turn.
  • a right side external mirror 8 is shown, which is on the outside of the curve.
  • a left side external mirror 10 on the inside of the curve is automatically adjusted and tracks accordingly by the invented system in the movement through the curve.
  • the limited visible area of the external mirror 10 is illustrated without tracking.
  • Reference number 14 indicates the widened visible area of an external mirror 10 equipped with tracking facilities.
  • FIG. 1 shows a tractor-trailer 2 , which is comprised of a tractor 4 and a trailer 6 in the course of a left turn at an intersection, that is to say, upon making a left turn.
  • a right side external mirror 8 is shown, which is on the outside of the curve.
  • a left side external mirror 10 on the inside of the curve is automatically adjusted and tracks accordingly by the invented system in the movement through the curve.
  • the expanded area of vision 14 representing that of the external, tracking mirror 10 , which is on the inside of the curve, allows the pedestrian or bicycle rider 16 to be seen by the driver of the tractor trailer in that same tracking mirror 10 , which is on the inside of the curve.
  • the pedestrian or bicycle rider 16 in the case of a mirror without tracking facilities, finds himself in the limited field of vision 12 and is not seen.
  • the external mirror 8 on the outside of the curve is customarily not automatically adjusted, since, as can be seen in FIG. 1, the rear end of the vehicle 2 , that is, the end of the trailer 6 , cannot be seen.
  • FIG. 2 shows a schematic wiring diagram in block style of an example embodiment of the invention.
  • This system which is in accord with the invention, is comprised of: a control apparatus 20 in the form of a microprocessor or micro-controller, a gyroscopic turn-rate sensor 22 , connected with control 20 and an electromotively operated mirror adjustment device 24 connected with control apparatus 20 , by which a mirror pane 26 of the inside curve, external mirror 10 can be adjusted.
  • a service module 30 is likewise connected with the control apparatus 20 .
  • the invented system can be manually turned off or on.
  • certain parameters of the invented system can be set, such as maximum outward travel, that is, the maximum outer adjustment limit of the external mirror 10 , sensitivity of the system, the latter being at the point of minimal angle of turning, where the system will activate, and automatic reset time—and the like.
  • some constant settings of the external mirror 10 can be defined or set in operation, in one instance, three different positionings in which the external mirror 10 can be run. To which of these positionings the mirror might be run can be made dependent on the turning motion of the vehicle.
  • connection of the control apparatus 20 with a (not more closely described) source of electrical current is indicated by reference number 32 .
  • This will be the current source of the individual vehicle.
  • the reference number 34 indicates the current supply for the mirror adjustment apparatus 24 .
  • the reference number 36 shows the feed of an input speed-signal to the control apparatus 20 which is drawn from the tachometer of the respective vehicle.
  • this is a gyroscopic-sensor, as it customarily is employed in video cameras, in order to avoid shaky pictures.
  • Such sensors are, for instance, offered by the firm Wuntronic GmbH in Kunststoff, Germany and are sold there.
  • FIG. 3 shows in schematic style, the tractor 4 with the left external mirror 10 and the therein integrated components of the system in accord with the invention.
  • Turn-rate sensor 22 , control apparatus 20 and the mirror adjustment device 24 are all integrally packaged into the mirror housing of the external mirror 10 .
  • the connection is made to the internal cab of the tractor 4 for the supply of current and to the service module 30 .
  • the mirror tracking system operates not only for forward motion, but also for the backing up of the vehicle.
